Since 2005, we’ve helped students improve their confidence and grades in trigonometry.

We’re especially proud of the fact that other educators (teachers and professors) and high profile members of the Princeton University Administration trust us with their children’s academic success and recommend our services to others.

Our trigonometry tutors are experts in math and can help break things down in a way that makes more sense to students. They can also help students with their approach – how to tackle a problem, how to organize their thinking, and how to record their work methodically so they don’t get confused.

Hi, I’m Joe.

What parents say about our Trigonometry tutors

Our team includes award-winning Princeton University undergrads and Master’s/PhD graduates who are rigorously screened and are extremely effective at communicating the material.

A quick “case study”: 

We were contacted by a family who would be returning to Israel within the next year.

The mother wanted us to help her sons, students at Princeton High School, prepare for the more demanding math program in Israel. The subject material to be covered included a mix of algebra, trigonometry, and geometry.

We matched her sons with Joseph, a public policy major at Princeton University who was valedictorian of his high school and who had significant tutoring experience with students from 12 to 17 years old in numerous subject areas (geometry, algebra, precalculus, trigonometry, chemistry, biology, and US and world history).

Here is the family’s feedback:

“Now that our sons have completed their series of tutorials with Joseph, I wanted to tell you how pleased we were with his work.

He is a fine tutor, with an excellent approach to kids. We would highly recommend him! Thanks for work well done.”

We receive messages like these every week.

We regularly track progress

Progress reports are shared after every session so you always know what’s going on.

A Real-Life Example: 

Student: Ava
Tutor: Miguel
Subject(s): Algebra 2/Trigonometry
Date: 11/06
Time Tutored: 19:00 – 20:45

Material Covered:

We did a fairly comprehensive review for Ava’s upcoming final exam.

We spent more than half of the session going over intermediate/advanced trigonometry problems. In all of these, one is expected to do more than the basic computations (e.g. sine of 30 degrees). Ava asked for assistance with a few problems from class worksheets. All of these problems have a few common strategies for finding a solution:

1. Find a right triangle (or triangles). Remember that a straight line represents 180 degrees; from this, one can make two right angles.

2. Use SOH-CAH-TOA to compute sides from angles. Remember to pick the trig function (sine, cosine, or tangent) that is most fitting, given the variables you have.

3. Simplify (cross-multiply, square both sides, isolate the variable, substitute, etc.). The goal is to solve for a variable (or two variables).

To make sure that she understands the material, I gave Ava a more challenging version of a problem from her worksheets. With some assistance, she was able to reach a solution. We should revisit this material.

Briefly, we reviewed the process for computing a Venn diagram with two categories (i.e. two circles). We will revisit the process of computing a three-circle Venn diagram.

At the end of the session, Ava did a few problems involving function transformations. The main idea here is to plug variables/equations into functions, perhaps more than once. After we worked through two worksheet problems, I gave Ava two harder practice problems. Although she may not need to plug in equations more than once, she should know how to do so, since the technique is identical.

Addresses common student issues

A deep understanding of the subject matter allows us to personalize our approach.

Why is Trigonometry important?

Trigonometry is not usually a standalone subject. It’s typically incorporated into Algebra 2 courses.

Why do some students struggle with Trigonometry?

As students transition from pre-algebra to algebra to algebra 2/trig, the material starts getting a lot more complicated.

Trigonometry introduces students to complex ideas like sines, cosines, tangents, laws, inverse functions, graphing, and more.
